Death sentence for murder

I believe the public need a serious threat if they commit a crime of murder That being a death sentence I think this will make people think again about carry a knife or any other weapon if the penalty is severe Jail sentence is not enough Let’s be honest a modern jail sentence appears to be a luxury, no bills to be paid, hot food provided, recreational activities- this ain’t punishment People need to have fear that if they commit this crime it is life or death
